一、centos6，git1.7.1
最近上手一个老项目，登录机器一看
centos6，vim编辑器没设置
安装配置一下vim吧
git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle
发现git还没发用，1.71版本
yum -y update
yum源也没法使用
这真是头疼，这么老的项目还拿出来维护干嘛，重构不得了！
二、从头开始
1.不用墨迹的了
阿里的yun源mirrors.cloud.aliyuncs.com/centos/6
清华的yum源 mirrors.tuna.tsinghua.edu.cn/centos/6
当然还有163，都无法使用了，里面只有一个readme文件，里面告诉你，centos的yum已经彻底不再维护
这不傻眼了呀
2.幸亏有个能用的
https://vault.centos.org/6.9/
进入yum源的配置文件夹：cd /etc/yum.repos.d/
把CentOS-* 全部删掉 （防止有问题可以备份下）
新建文件 CentOS-Base.repo
里面加入内容
代码语言：javascript复制[base]
name=CentOS-6
failovermethod=priority
baseurl=https://vault.centos.org/6.9/os/x86_64/
gpgcheck=0然后执行
yum clean all yum makecache
3.如果makecache也报错timeout等相关问题
这里也可以更换另一个可用源
.repo文件内容，全部更新为如下：版本6.6可以更换为自己需要的
代码语言：javascript复制# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
